It’s March 14, 2015, which, in North America at least, makes it Pi Day (3/14/15), a day where people celebrate the most well-known mathematical constant with delicious baked goods and puns.

But in Middle-earth, the magical and engrossing world created by J.R.R. Tolkien as the setting for his tales of rings, hobbits, and adventure, Pi Day could coincide with the elven celebration of the Diptera! In Quenya, the ceremonial language of the high elves in Middle-earth, the word “fly” (in the entomological sense) translates directly to pí.

Coincidentally, flies actually make their debut in the world of Middle-earth on March 15, 3019 (The Return of the King, Book Six, Chapter II – The Land of Shadow) as Frodo and Sam wander through a riverbed deep within Mordor. Tolkien writes:

To their surprise they came upon dark pools fed by threads of water trickling down from some source higher up in the valley. Upon its outer marges under the westward mountains Mordor was a dying land, but it was not yet dead. And here things still grew, harsh, twisted, bitter, struggling for life. In the glens of the Morgai on the other side of the valley low scrubby trees lurked and clung, coarse grey grass-tussocks fought with the stones, and withered mosses crawled on them; and everywhere great writhing, tangled brambles sprawled. Some had long stabbing thorns, some hooked barbs that rent like knives. The sullen shrivelled leaves of a past year hung on them, grating and rattling in the sad airs, but their maggot-ridden buds were only just opening. Flies, dun or grey, or black, marked like orcs with a red eye-shaped blotch, buzzed and stung; and above the briar-thickets clouds of hungry midges danced and reeled.

The dancing midge clouds are easily explained, but I spent a lot of time trying to find a fly species that would fit Tolkien’s description. It turns out that “dun or grey, or black, marked like orcs with a red eye-shaped blotch” is a surprisingly rare combination in the Diptera. In fact, I couldn’t find any species of flies that could be described as dark with red splotches! Certainly there are species that are dark with red heads, including micropezids in the genus Scipopus, or signal flies in the genus Bromophila (as recently discussed by Piotr Naskrecki), and many flies are known for literally having red eyes (think of your friendly kitchen Drosophila), but unlike beetles, red blotches or spots seem to be rare in flies.

The only solution I could come up with that fit the general description and habitat of these Morgai flies was perhaps a species of Chrysopilus snipe fly (Rhagionidae), commonly called golden-backed snipe flies here in regular Earth. These flies have a blanket of magnificent golden pile on the top of their thorax, which can be brushed off giving the appearance of the Eye of Sauron (although they are certainly not blood suckers or pests). Perhaps under the evil influence of Sauron, a new species of  Chrysopilus arose in Morgai, developed a taste for orc blood, and took to the air to reign terror from the skies.

So on this Pí day, I hope you’ll not only herald the popular mathematical constants, but also the dipteran variables that make our natural history interesting, and our literary history magical.

Of course, the best possible way to celebrate would be to follow James Gilbert’s lead and make a Pí Pie for Pi Day. Mmmm, pie.

Footnote: In the recent video game Middle-earth: Shadow of Mordor, Morgai flies were depicted as eusocial, living in paper hives, and able to drive off nearby orcs with a well-placed arrow. While I may be taking liberties with fly evolution to make a red, blood-sucking snipe fly, calling what are clearly social wasps “flies” gives WB Games a taxonomy fail index of 58. Now there’s some math for you.

The trailer for Jurassic World, the latest instalment in the Jurassic Park franchise, was released today, and well… see for yourself.

While scientists have apparently figured out how to genetically modify dinosaurs (which I thought was the entire premise of the original when they spliced frog DNA into ancient Dino DNA, but whatever, GM-OH NOES!), they still haven’t hired an entomologist to tell them which amber inclusions are mosquitoes (family Culicidae), and which are crane flies (family Tipulidae).

Oops.

Oops.

No big deal though, crane flies and mosquitoes are close enough, right? Well, actually they’re about as closely related to one another as velociraptors are to sea turtles (and only a little more closely related than humans are to Tyrannosaurus rex).

I think we can all agree that Jurassic World would have a much different mood if it climaxed with this

than it does with this

So for all you Hollywood producers out there looking for an entomology consultant to save you from embarrassing oversights, have your people call my people; we can fix this. But in the meantime, save me a seat when Jurassic World hits theatres.

P.S. About that Mosasaur. While we know marine mammals like killer whales can be bitten by mosquitoes (a captive killer whale in San Antonio contracted and later died of West Nile Virus back in 2007), the odds of a mosquito biting a wild mosasaur in the ocean, and then flying, fully leaden with blood, back to shore, only to be immediately entombed in sap running down a tree trunk and preserved for a few million years as an amber inclusion, are a bit of a stretch.

There’s a chance I may be overthinking this.

Skeleton just might be the most insane sport in the Winter Olympics: athletes run as fast as they can, lay down head-first on what is essentially a lunch tray with blades affixed to the bottom, and then go barreling down an icy tube at speeds of up to 140 km/h, experiencing up to 5x the force of gravity on tight turns, all with their faces mere inches from the the surface of the track. I can only assume there was alcohol involved the first time somebody thought to try this, but it has since become one of the most exhilarating sports to watch in the Winter Olympics.

Our insect competitors may not be going at the break-neck pace of human Skeletoners, but I think we can agree the end result is just as exhilarating. Hailing from the Amazon and proudly representing Team Arthropoda, meet Euglossa orchid bees and their very own death-defying Skeleton courses, Coryanthes bucket orchids.

Incredible, is it not? It’s fitting that the Insect Skeleton event starts today considering yesterday was Darwin Day, the 205th anniversary of Charles Darwin’s birth. Darwin was particularly enamoured by orchids and their convoluted reproduction strategies, and wrote an entire book on the subject in 1895, specifically marveling at the intricacy of Coryanthes pollination biology.

Here in Canada, cross-country skiing is a favourite winter pastime, with people eagerly awaiting the first snow by waxing their skis and stocking up on hot chocolate for after their trek through the wilderness. The Norwegians however, have shown this week that cross-country skiing is their sport at the moment, having taken home 8 medals in cross-country skiing events (6 in cross-country, 2 in biathlon) already!

In my experiences with cross-country skiing, I found it was much easier to stay upright when moving, and that stopping generally resulted in a cold, snowy crash followed by some awkward struggling to get back on my skis.

In a way, that’s a lot like Chionea winter crane flies (Limoniidae — or Tipulidae, depending on who you ask), a genus of wingless flies which are commonly seen running across the snow on sunny days across North America and Europe. It’s been reported repeatedly that when on snow, Chionea are in constant motion. Why might this be? Princeton entomologist Warner Marchand believed it might have been to avoid freezing to the snow, a conclusion he came to after observing winter crane flies on the balcony of his vacation home over several days. Sigmund Hagvar, an entomologist working in Oslo, Norway, on the other hand, sat and counted the number of steps Chionea araneoides individuals took across the snow, and found they took ~85 steps/min when temperatures approached 0°C, while slowing to only ~40 steps/min when the air temperature was -5°C! He suggests that the continuous movement may enable these flies to live and breed at such cold temperatures, noting that at -6°C they begin to go into chill coma and die. With temperatures expected to be just above freezing at the Sochi Cross-Country Skiing this week, Chionea araneoides may be hot-stepping their way to a medal!

While many in North America may recognize the Ski Jump from the brief clip fully encapsulating the agony of defeat in ABC’s Wide World of Sports intro, this event is quite popular in northern Europe. Supposedly originating in Norway when an army officer was showing off for his troops in the late 1800s, the men’s ski jump has been included in every Winter Olympics to date, while 2014 marks the first time women have been allowed to fling themselves off a mountain and sore for Olympic gold!

Little known fact: the bar that ski jumpers sit on at the top of the hill before launching themselves down the slope used to be a raw log imported from the jungles of Central America to help encourage international inclusion*, and with it would often come gliding ants (conveniently for this story Cephalotes atratus), who would show off their own ability to fly!

So how do ants measure up to our advanced aerodynamics, years of practice and training, and our pursuit for the thrill of victory? Surprisingly well, all things considered. With absolutely perfect form achieved with models in a wind tunnel, humans can attain a maximum horizontal glide of between 1.13m and 1.34m for every metre they drop, depending on the in-flight technique employed by the athlete. That means that when the women ski jumpers take off later today, they’ll be aiming for flights of nearly 100 metres, finishing with safe and graceful landings down the mountain, while only** falling about 80 metres!

By comparison, Cephalotes gliding ants have been found to majestically sore about 0.18m for every metre dropped. While they certainly won’t be challenging our athletes, it is more than sufficient to allow the ants to glide a few feet towards their tree trunk should they fall from their arboreal nests, avoiding a very long hike from the ground!

I guess it all comes back to form vs. function, and in this contest, I think we can clearly consider Team Arthropoda the winner.

It’s that time again, when nations around the world send their top athletes to compete in the Winter Olympics for precious medals, national pride and bragging rights for another 4 years! The 22nd Winter Olympic Games are being held in sunny Sochi, Russia this year, which opens the door for a new team to make its first Winter Olympics: Team Arthropoda!

Throughout the games, these industrious insects, sporting spiders, and other athletic arthropods will be showing they can compete with the best of us mammals, especially under the magnifying glass of international attention inherent with the Olympics — something insects and their kin are used to dealing with by now!

The 22nd Winter Olympiad officially began Friday evening with the opening ceremonies, and extravagant event showing off the natural wonders, history and culture of Russia, including an early shout-out to taxonomist-turned-novelist Vladimir Nabokov and his beloved butterflies! The athletes from each nation paraded into the Fisht Olympic Stadium lead by their flag-bearer, an honour generally bestowed on an athlete considered to be a leader for the team.

Meanwhile, directly under the Olympic flag on the main stage, Team Arthropoda selected the newly-named Australian jumping spider Maratus avibus to carry their colours, for obvious reasons. Described just in time for these Olympics by Jürgen Otto and David Hill, Maratus avibus is the newest delegate of the peacock spiders, and proudly waved Team Arthropoda’s flag as high as he possibly could, even if it was only a few millimeters.

Stay tuned throughout the 2014 Winter Olympics to find out how Team Arthropoda stacks up against the rest of the world!

There’s a pretty remarkable fly photograph making the rounds of social media today, and while it originally had me going “Oooooh!”, the more I think about it, the more I feel like we’re staring at clouds.

It started when Ziya Tong tweeted a photo of a Goniurellia tridens (a fruit fly in the family Tephritidae) displaying its wings:

Things I didn’t expect to do today: talk about flies live on BBC Radio 2!

I made my radio debut this afternoon when I helped out with Simon Mayo’s Homework Sucks! segment of Drivetime. Homework Sucks! is a regular feature where listeners send in questions (whether from their kids homework or otherwise), and the BBC finds experts to give a hand with the answers.

Today’s question: Can insects smell, and if so, how far away can they smell things? You can listen to my answer thanks to the recorded and archived edition of the day’s episode on the BBC website (skip to 1:39:30 for my segment).

So how’d my first brush with the mainstream media happen? I got a call from Richard Levine, the Public Affairs Officer for the Entomological Society of America, asking if I’d be interested in the opportunity to speak on the BBC about how flies smell. There was a catch though: the segment was going to be live, and was going to start in less than 10 minutes! So, I ran across the lab, grabbed R.F. Chapman’s The Insects: Structure and Function off the shelf, quickly refreshed my memory on volatile chemoreception in insects, then jumped on Google Scholar to see if I could find an estimate of how far away some insects can sense scents (which isn’t easy when your fingers are quivering from the adrenaline rush & nerves). Before I even had Chapman opened, a BBC producer had called me to explain what was going to happen and to get my details figured out, and then 5 minutes later another producer called and I was on hold waiting for my opportunity to go on the air! A few minutes after that I had given my spiel, and was sitting at my desk wondering what had just happened, while trying to dissect what I had said and whether I could recall making any goofs!

While I was sure I stumbled and mumbled my way through it at the time, I actually think I sounded pretty coherent after listening to the recording, and it would seem people enjoyed it as well (thanks for the feedback to those who’ve given it!). I’m giving a lot of the credit for me not sounding like a bumbling n00b to Breaking Bio, which has provided me the opportunity to practice talking about science in an informal setting, and in a digital format. It just goes to show that goofing around on the internet with your friends can have surprising benefits for your work!

Evolutionary biology is dramatic. Species come, and species go. Simple, random mutations allow organisms to exploit bold new resources. A year’s worth of field data can hinge on the immediate availability of duct tape. You get the idea.

After discussing these thoughts on Twitter with @Sciencegurlz0, @sciliz & @cbahlai this evening, we’ve come up with a way of conveying the events occurring in research labs and backyards around the world in a manner befitting their seriousness: a YouTube series featuring abstracts of evolutionary biology papers being read dramatically by professional actors.

Picture it: Hugh Jackman belting out the abstract for “Macrophages are required for adult salamander limb regeneration“, or Jenny McCarthy sharing her talents to pass along the “Annual Report to the Nation on the Status of Cancer, 1975–2009, Featuring the Burden and Trends in Human Papillomavirus (HPV)–Associated Cancers and HPV Vaccination Coverage Levels“, or Sir Patrick Stewart providing a dramatic reading of, well, anything really (although I’d suggest “Space travel directly induces skeletal muscle atrophy“). Yes, I believe this is what the internet was made for.

While the videos would be highly entertaining and have the potential to go viral, I’d accompany them with explanatory write ups of the paper in question. The silly-sounding readings would serve as the hook to pique people’s interest in the science (i.e. what on earth is Hugh Jackman singing about), and encourage them to read more about the paper with the help of a skillful synopsis provided by one of the many talented science writers currently at work on the web.

While I think the idea has a lot of potential, we don’t have the connections to make it a reality (I’m not sure I know any actors personally, famous or otherwise). So, I’m throwing the idea out into the web with the hopes that a connected and creative person out there will run with it. The online science community is a large and diverse place, and I’m sure there’s someone who can make this a reality.

The only thing I ask is that you send me a link when you roll it out, because I’d really love to watch Samuel L. Jackson ad lib “Germs on a Plane: Aircraft, International Travel, and the Global Spread of Disease“.

Hey blog, what’s new? Oh, that’s right, nothing lately… My bad. To say the past few months have been hectic would be a bit of an understatement, but that’s a tale for another time. To kickstart my bloggy brain cells, I figured I’d ease back into it with a Tuesday Tune, then maybe a new photo, and quite possibly a rage-driven rant observation on society later this week. Fun!

Normally with Tuesday Tunes we get a song that may have insects in the title, the lyrics, or maybe a cameo in a video. This week’s song not only features a great title & lyrics, plus a psychedelic & morphologically awesome video, but also some killer album art!

No, I don’t know why a mosquito is changing a baby, but damn if that’s not a great album cover!

Meet Mosquito by indie rockers Yeah Yeah Yeahs (be sure to watch to the end) –

If you thought natural selection would punish a hyper-obvious mosquito like the one in the video, you’d normally be correct. However, the psychedelic Psorophora ferox would beg to differ!
